One of the first times we hear Töben speak in his documentary is whilst he is giving us a tour of Crematorium I, which contains the first gas chamber used to kill people at Auschwitz. He starts by talking about one of the external doors of the building before moving inside the vestibule and towards the gas chamber. There, he then points out that the old wooden door separating the two rooms was not air-tight, and that this is a serious problem for those who believe the room behind it was used to gas people. Later in the documentary, Töben and the unknown Australian narrator go on to say that there never was any gas chambers in the Nazi concentration camps, and that all the so-called gas chambers we see today are fakes. They also claim that Zyklon-B (the cyanide based pesticide used to gas people) was never used to kill, but instead used to save lives by sterilising clothing.

Before I refute the documentary’s claims, we first must discuss how the gas chambers operated. So as not to cause a panic, victims were told they were about to take a shower and undergo delousing. Some were even given soap and a towel. They were then led into a chamber where they undressed before being led into a gas chamber, which was disguised as a shower facility. The doors were then locked and an SS officer dumped Zyklon-B pellets through vents in the roof or the sides of the gas chamber. The cyanide-based pesticide, Zyklon-B, kills by preventing cells in the victims’ body from using oxygen to make energy. It does this by binding to iron found in an enzyme in the mitochondria of cells called cytochrome C oxidase. It then prevents the binding of oxygen at the active site, preventing the synthesis of adenosine triphosphate (ATP) resulting in chemical asphyxiation. The victims were dead within 10-20 minutes.

People wearing gas masks then dragged the bodies from the chamber, removed their glasses, artificial limbs, jewellery, and any dental work was extracted so the gold could be removed and melted down. The corpses were burned in the incinerators and ashes were buried, thrown in a river, or used as fertiliser.

Crematorium I

At around the 50-minute mark in the documentary, the subject of Crematorium I gets mentioned again – this time by the unknown Australian narrator, who believes the gas chamber to be a fake.

“The only chamber left still undestroyed is in the Auschwitz main camp. But it too is a comedy of errors. Whereas the prisoners had a swimming pool next to their barracks, the Germans supposedly built this gas chamber only 20 paces from their SS restaurant and hospital.”

This is one of many examples of the documentary trying to convince the viewer that these concentration/death camps were actually really nice places to stay. Even though the presence of this swimming pool at Auschwitz is mentioned multiple times throughout the movie, it ignores the fact that it was originally built as a water reservoir for the purpose of firefighting. It was not until 1943, when the then-commandant at Auschwitz, Arthur Liebehenschel, ordered the construction of diving boards to be constructed. Even then, it was only accessible to SS men and certain privileged Aryan prisoners employed as inmate-functionaries in the camp. This information is easy to find, yet the movie would have you believe that the existence of this swimming pool is being repressed, and tour guides purposefully don’t show it on their tours.

Likewise, Crematorium I did not always contain a gas chamber. Originally it was equipped with two (later three) cremation ovens with a morgue room behind them. It was not until late in 1941 that this morgue room was sealed up and five holes were cut into the roof, allowing Zyklon-B to be dropped in so it could be briefly used as a gas chamber. There were major issues using this retrofitted gas chamber, such as its proximity to other buildings. This is something the narrator of the movie actually gets correct.

“According to the polish tour guide, the only method of getting this poisonous gas out of this large chamber was to open two flimsy unsealed doors and let the wind blow hundreds of cubic meters of poisonous gas out onto the street.”

According to, ‘Anatomy of the Auschwitz Death Camp‘, a large fan was installed to remove the gas after it was used to murder people. However, the proximity of nearby buildings was still a problem. For this reason and more, the gas chamber in Crematorium I was only used for a small amount of time – from February 15, 1942 until sometime in the fall of 1942, when the murder operations moved out to the newly-constructed purposely built gas chambers and crematoriums in Auschwitz II–Birkenau.

“The only evidence we could find on the inside of the chamber was evidence of incompetence. The roof holes have once again been crudely smashed through the concrete. Fixtures that probably belonged to toilets have been removed, but proving this alleged gas chamber once had a toilet. And then there is the door. A flimsy wooden construction with a window and the locking device on the inside. A door that could easily be kicked out.”

Just as Crematorium I did not start its life at Auschwitz as a gas chamber, it did not end its time there as a crematorium. In 1944, the building was converted into an air raid shelter. Its ovens were dismantled, the holes that were once used to drop Zyklon-B into were filled in, toilets were installed, and the gas chamber was subdivided with strong walls to support the ceiling. This is probably one of the reasons why it remained after the war when attempts were made by the Nazis to destroy evidence of these gas chambers.

After the war, the camp was turned into a museum and, using blueprints dated September 25, 1941 and eyewitness testimonies, Chamber 1 was restored. This is why it looks like the holes in the roof of the gas chamber have been smashed – because they have been, just like the originals were.

I know this is painfully obvious, but the flimsy wooden door he is talking about is not the same air-tight door used when the building was used to gas people.

“Back up on the roof, Doctor Töben points out the crematorium chimney. A chimney that is not found on any aerial photos at the time, but we believe it was added later by the Russians. But whoever added it did not bother even attaching it to the building.”

Both the the ovens and the chimney were rebuilt in 1947 by the Soviets, who decided not to attach the two together. Maybe they did not like the idea of making the facility functional again after such a short amount of time… who knows, but what we do know is that this reconstruction took place. Despite this being common knowledge, the documentary is trying to push the idea that this is secret information, despite that fact that there is a plaque outside crematorium I that talks about the history of the building.

Something that I have found both quite interesting and eerie is the blue staining of the walls in some of the surviving gas chambers. This blue colour is a result of the hydrogen cyanide from the Zyklon-B reacting with Iron in the walls to make a dark blue pigment called Prussian Blue. This pigment has been used in many famous artworks such as Vincent Van Gogh’s Starry Night, or the Great Wave off Kanagawa by Hohusai.

Nearly all of the gas chambers were destroyed by the Nazis towards the end of the war in an attempt to destroy evidence of their atrocities. This exposed these cyanide-based compounds (which only penetrated to a depth of around 10 micrometers) to the elements, eventually leading to the blue colour fading away. However, the gas chamber at the Majdanek concentration camp was captured intact, and is the best example of this blue staining.

When confronted with this glaring evidence, Töben and the unnamed Australian narrator say that there is no evidence of these compounds found in the rooms used to gas humans.

“The tinge of blue you may see here comes from the flashed photos and not any staining from Zyklon-B on the walls – because there isn’t any.”

It also becomes clear at this point that the documentary is hinting at results from the Leuchter report. This report was used to defend the person this movie is dedicated to, Ernst Zundele, who was put on trial for violating Canadian laws against distributing false news when he published the pamphlet, ‘Did Six Million Really Die?’

The report analysed multiple pieces of brick and the remains of the crematoria and gas chambers at Auschwitz (without the camps permission). The report stated that it was unable to find evidence of any cyanide-based compounds in the homicidal gas chambers and, therefore, they could not have been used to kill people. It goes on to say that it was able to find evidence of these compounds in Auschwitz’s delousing chambers.

This is a huge cornerstone of the revisionist (AKA holocaust denialist) conspiracy theory. They believe that Zyklon-B was only used for delousing infested clothing, and that it was not used to murder people. In the documentary, this section is even called “real gas chambers made for saving lives”.

There are multiple crippling errors with the Leuchter report, starting with the fact that the synthesis of these iron-based cyanide compounds is by no means a categorical sign of cyanide exposure. It requires a very high concentration of cyanide and a source of iron.

There was also a problem with sampling in the Leuchter report. Rather than just testing the surface of the gas chambers, entire chunks of brick and mortar were taken and ground up, then analysed. This diluted these cyanaide-based compounds to below the detectable amount for the lab they hired.

The reason why they were able to decide the compounds using the same method in the walls of the delousing chambers was for two reasons. The first is that they were not exposed to the elements, and the second is that Zyklon-B was used in these rooms in a much higher concentration, and for a far longer time, in order to kill the parasites. Because of crackpots like Töben and the unnamed Australian narrator, competent scientist have tested the walls and found, under double-blind conditions, evidence of cyanide-based compounds.

In my opinion the “fake gas chamber” and the lack of cyanide-based compounds detected in the rubble of the gas chambers is the best evidence these “revisionists” have that the holocaust was faked. None of it stands up against even the slightest bit of scrutiny and, most of the time, it takes a massive leap of faith to believe in.

As I said at the beginning, I could spend months correcting every mistake made in this documentary but, quite frankly, that would be a waste of my time. After the publication of my original video on the subject, and seeing the backlash I got – including my content being reported as “hate speech”, I can tell that there is nothing I could say that could change the minds of these people. They want an excuse to explain their bigotry, and pretending the holocaust did not happen gives them the perfect excuse.
